Did one of the versions fail in it? 64 is test case for that: 8*8 =64. The other versions though complained number too big to convert to int.

This program is of course slow for biggest numbers, but it would be also slow to multiply from permutations of prime factors (maybe faster with biggest ones, but so what).

Also this code has benefit of not being directly factoring, which one question deals with, that is why I did not yet want to send my factoring function before he finish. If he is clever, he can catch some idea from this.

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
the function that I created to find the ...

Write a C program that should create a 10 element array of random integers (0 to 9). The program should total all of the numbers in the odd positions of the array and compare them with the total of the numbers in the even positions of the array and indicate ...
